Core Innovation
Extends fMRI cognitive taskonomy from single-source to multi-source transfer learning:
- Traditional: one-to-one transfer (single source → target)
- This work: multi-source transfer quantifying task relations across multiple source tasks simultaneously
Key Methodology
- Masked fMRI Reconstruction as self-supervised objective
- Transfer Relation Quantification among cognitive task states
- Multi-Source Taskonomy capturing shared and specialized neural processes
Technical Framework
- Self-supervised learning via masked reconstruction
- Transfer learning analysis across fMRI task states
- Quantification of task similarity/dissimilarity
Applications
- Cognitive task taxonomy construction
- Neural representation analysis
- Brain encoding model comparison
- Cross-task transfer prediction
Key Concepts
- Taskonomy: Task relationship taxonomy based on neural representations
- Transfer Learning: Knowledge transfer between cognitive tasks
- Masked Reconstruction: Self-supervised objective for neural representation learning
